There are several species of Larkspur, and depending on the species and the climate in which it is grown, Larkspur can be either a perennial or an annual. Related to the buttercup, Larkspurs are complex like orchids, comprised of tall, beautiful spikes and flowers consisting of petals and sepals. Foliage is lacy and regal, with heights exceeding 36 inches. This flower is a favorite for both fresh and dried bouquets.
Whether planting along fence lines, as borders, or in groupings, select a well-draining area. Larkspur plants like water, but not soggy conditions that could cause rotting. Plant seeds close to the top layer of soil, since they need plenty of sun to germinate. Seeds germinate in about a week and grow best in cooler weather. Excessive heat and frost are hazardous to this plant’s survival.
This is a toxic plant, poisonous to humans and animals, and highly dangerous for cattle. Larkspur is self-seeding, which creates a problem for cattle owners. Aphids can be a nuisance, so treat with an organic insecticide.
